How can I reuse or recycle Christmas tree needles?

I know a lot of people go for no-drop types of Christmas tree these days but some of them still shed like billy-o.

Pine needles can be composted – they can be quite acidic though so if that’s undesirable, make sure you balance them out in your heap with some alkali things (wood ash, for example). Also don’t drop a heavy layer into the heap all in one place – they sit pretty densely together and can restrict airflow.
